Testosterone Propionate Injection 100 mg/mL, 10 mL

Description

Testosterone propionate injection at 100 mg per mL in a sesame oil vehicle with benzyl alcohol, supplied as a 10 mL multiple-dose vial holding 1,000 mg of ester. No current United States human product holds FDA approval at this ester, although other testosterone esters do. Schedule III. Research use only, not for human consumption, adults 21 and over.

The specification

Sesame oil and benzyl alcohol, both named and both part of the specification. The preservative is what makes a multiple-dose container defensible once it has been entered.

Catalogued in the injectable shelf, alongside the rest of the anabolics reference stock.

Position under United States law

There is no currently marketed United States product at this ester. Other testosterone esters are approved and marketed, which means a pharmaceutical equivalent exists for the molecule but not for this particular ester, and that distinction is the useful fact about testosterone propionate injection. It is Schedule III. See the FDA’s drug approvals and databases and the DEA’s drug scheduling pages.

Vehicle, preservative and the propionate ester

Benzyl alcohol is an antimicrobial preservative and nothing else; it is not a co-solvent and it does not raise the solubility of the steroid. Sesame oil does that work. Keeping the two functions separate is the difference between reading a label and skimming it.

The ester is three carbons on the 17 beta hydroxyl, taking testosterone from roughly 288.4 to 344.5. Parent steroid is about 84 percent of the labelled mass for testosterone propionate injection, the highest fraction among the testosterone esters in this catalogue, and short esters hydrolyse faster than long ones as a matter of chemistry.

Milligrams per vial for testosterone propionate injection

100 mg per millilitre across 10 millilitres is 1,000 mg of ester. At $95 that is $0.095 per milligram of ester, or about $0.113 per milligram of testosterone. The laboratory vial at the same concentration and volume divides to $0.059.

Same quantity, different grade, different price, both printed. Why price per milligram beats the price on the bottle and check the lab before you check the numbers cover what separates them.

Specification and certificate

The specification is what testosterone propionate injection is sold against, and the certificate is the evidence for it. Purity by HPLC, expressed as percent of total peak area. Identity by mass spectrometry against the expected molecular mass. Residual solvent in parts per million. Appearance and, where the dosage form calls for it, uniformity of content across units. The contract laboratory producing those figures is independent of this company and always has been, and the lot number on the container of testosterone propionate injection is the index back to its report.

Our guide to reading a certificate of analysis works through one of these documents line by line, and the full set sits on the lab results page.

What this page does not contain

No dosing tables. No protocols. No comparisons of potency between compounds, and no description of what testosterone propionate injection does in a living organism. Those are not omissions we will fill in on request, including in order notes and in messages to our staff.

The reasoning is on the public record. The pattern the FDA has pursued in writing is pages that pair a research-use-only line with human outcomes, protocols or quantities for testosterone propionate injection, and the disclaimer does not rescue the page it sits on. Research use only is not a legal strategy goes through the letters, and the FDA’s drug information section carries the agency’s own material.

Traceability

Lot number first, everything else second. The number printed on the container is the key to the assay report, the receipt date, the method and the archive copy, and it is the only part of the label that cannot be reconstructed from the catalogue. Content per unit, container count and storage conditions for testosterone propionate injection are also on the label and on the listing. If the two disagree, the label is the document that travelled with the material, so the label wins and we want to hear about it.

Research use only, not for human consumption, adults 21 and over, with purchase restrictions by state. Where a state excludes this compound the listing says so before checkout rather than after it. Nothing on this page is offered as a drug, a supplement or a food. The certificate for the lot you receive, and the certificates for the lots we withdrew, are on the lab results page.

US regulatory status. No testosterone propionate product is currently marketed in the United States, although other testosterone esters are.
